ren-MACHINE sLEn.

Application filed July 2,

To all whom t m04/ concern.'

Be it known that I, FREDERICK B. Gnorr, a citizen of the United States, residing at Glovcrsville in the county ofFulton and State of New York, have invented certainV so mounted and balanced that the same may be easily rocked on its pivot to raise the saw when itis desired to transport the machine.

`Another object of the invention consists in the .provision of a power operated ice cutting mechanism and adjustable guides therefor, whereby the machine may be guided along a straightV line without attention on the part of the operator, including depth gages for the cutter carrying frame for regulating the depth of cut of the saw.

Another and very importa-nt object of the invention is the provision of an iceA cutting mechanism of thetype above set forth inl which the parts are extremely simple c in construction, easily assembled, rigid and durable, highly Vefficient in operation, practical, and capable of being manufactured at a very low cost whereby its commercial pos` sibilities are greatly enhanced.

With these objects in view and others which will be manifest and suggested as the purpose and nature of my Vinvention are revealed in the following specification and drawing wherein I have shown a preferred embodiment thereof,

Figure 1 is a plan view of the ice cutting apparatus, Y

Fig. 2 is a side view thereof,

Fig. 3 is a front view, partly in section,

Fig. f1 is a detached view of the sled or runners,

Fig. 5 is a detail view of one of the guide supporting rods,

Figs. 6 and 7 are detail views of the guides or cutters, and,

Fig. 8 is a detached view of one of the depth gages.

`Referring now to the drawings wherein 1921. Serial No. 482,286.

like parts designate corresponding parts throughout, the supporting sled forthemo-V tor frame and power saw consists of a pair of runners 5, 6,v which areconnected by a pair of transverse cross bars'7, 8, at the front and rear thereof, the ends of said bars being yrecessed in the tops of the runners and .rigidly secured thereto by lag screws or other fastening'elements .to forma strong,

durable, and rigid supporting structure for s the motor frame now to be described in def tail. 's' .Y z f- The motor framewhich also'supports the power saw consistsof apairjof longitudinally extending beams or bars 9,. 10, which( are connected by transversely extending, flat. beams 11, 12, to which the vertical supports 13 are secured whereby the power operating mechanism such asa gasoline engine, electric motor or their equivalent may be secured in the manner shown particularly by Figs. 1 and 2. ,p z Referring to these figures, it will be observed that the side bars 9, 10 are pivotally mounted for rocking movement on a rod or v aXle 14 which extends through ,the runners 5 and 6, substantially intermediate the ends thereof. The side beams 9, 10 extend forwardly of the runner members at theirfor.- ward ends, and are provided with bearings 15 to support a shaft 16 which includes an arbor at one end to. carry anice cutting saw 17. The sawl? is provided. with the usual semi-cylindrical .guardl or casing y21 mounted on the'end of one of the longitudi-y nal beams above referred to.' V l Secured at 2%- to the rear of the beamsf), 10, a handle structure forthe motor frame, consisting of a pair of sidefbars 22, 23 and connected by cross rods 25 whcrebyn'the :nio-` tor frame may be rocked on its pivot or shaft 14 as will be readily understood fromy an inspection of Fig. 2. Adjustably secured to the member 11 of themotor frame and.

between the longitudinally extending -side members 9 and 10 are a pair of depth gages 26 with lower curved ends 27 which normally engage the ice field. The stock portions of the gages 26 are each provided with a plurality of spaced apertures indicated at- 28 in Fig. 8 to receive holding bolts, to provide for the adjustment of the gages, and thus control the depth of cut of the saws.

The machine is also provided with front and rear gage supporting shafts 29, 30, the

.front shaft being lrotatable in a bearing 8l.,

secured to; thev side beam l() and provided with a gage 32 adjustable in any one of a number of apertures 33 Vformed in the shaft 36 is connected tothe rear shaft-'30 wherebyy 29 which may thus be positioned iny direct'/ alinement with the rear gage 34 whereby the machine may be guided as isv well un.- derstood. The rear shaft 30 extends through the side runners', 6V of'the sled" and beyond opposite sides thereof, the eX- tended endy of the'said shaft 30 being provided with an ustable gage 35. A handlesaidshaft maybe oscillated to rotate the gages to enterthem` into thev cut or groove' made in the ice, or remove them therefrom, as required. p

vThe gage carrying shafts 29 and 30 connected 'together as shownat 42, sothat upon the operation of the handle 36 both sets of gagesV 32 and 37 will be simultaneously operated, `as above described. Y

Secured-on the rear cross bar 8 of the sled,

j isa. standard` 4Oprovided with a curved member38 attached to its'upper end, saidV arm 38V being; in turnv connected by Ya coiled spring 39 tothe side runner (j as shown in Figure- The curved member 38 is thus yieldably supported at its outer end by the spring39. VExtending laterally from the handle 36 is an varm 43 which projects beneath the Vcurved yieldably supported member. 38 and will hold the handle from forward movementrby engaging the standard 4l, and thus preventl the gage members 32 and 34 Vfrom.rearward movement. beyond the ver- Ytical. As the rmachine moves forwardly the friction of. the members 32r and 34 Vagainst Y the sides of the sc-ore. or channel formed by the saw 17 will be sulficient to retain Y the'members 32 and 34 in vertical position and the contact of the armr43 againstc the standard 41 will prevent them from being moved to the rear, asgwill be obvious.

Y When theV gage members 32 and 34 are toy be removed from the scorel or channel at the end of the trip', or when the machine Y to be removed` theV handle 36 is moved rear- K cause the arm 43 to travel beneath the.

wardly into the position shown by dotted lines in Figure 2 which movement will curved member 38 which latter member will bei caused by theV spring 39 to press with sui'cient forcey against the' arm 43 to hold are the handle in its rearward lposition and likewise hold theL gage members `in with* drawn and inoperative position.

@By this construction, it will be readily` y apparent that the'` operator may tilt Vand rock the motor frame and sawv carried thereby on the pivot I4 and lock the samerin posi'- tion, it being understood that the depth of cut is regulated by adjusting the depth gages 26 above referred to, and by regulat; ing thespeed of the motor through thefleX-V ible element 40 connected to the handle *de-V vice 22. IV hen the machine is oncestarted the same will work regularly and through the partof the operator.

al straight path without the attention `on Q g 70 'i In the accompanying drawings, Ihave illustrated my invention embodied in one' YformY by way of example, and which kin practice has'beenl found tobe highly satis-` factory in obtainingthe'desiredV results. /It will be obviousfhowever that other embodiments may be adopted andk that various changes in the details ofconstruction may be resorted to by those .skilled in the art without departingfrom the spirit and scope Carrying 'a saw and mounted to tilt uponV said platform, a, shaft mounted `upon said sledand extending beyond thesame, a: gage member carried'by said shaft, anollierating` handle extending from'said shaft, a curved member` supported at one end from saidV sled, a spring connecting said curved mem-' ber at the other end to said sled, and an arm extending from said operating handle and beneath said curved member andheld in frictionalcontact therewith by the `action of said spring.

In testimony whereof I ai'iix my signa-4 ture hereto- FREDERICK R. GROFF
